🌿 Care Guide
Watering
Provide deep, infrequent irrigation to moisten the full root zone (approx. 12 inches deep), typically 1 inch of water per week. Avoid overhead watering to minimize disease; water at the base in the morning so foliage dries quickly.
Fertilizer
Apply a balanced organic or 10-10-10 NPK fertilizer in early spring at leaf-out. Follow with a low-nitrogen, high-phosphorus formula after the first bloom flush to support subsequent flowering. Do not fertilize newly planted roses until after their first flowering cycle.
Pruning
Prune in late winter or early spring before new growth begins. Remove dead, diseased, or crossing branches and thin out weak stems. Deadhead spent blooms throughout the season to encourage continuous re-blooming.
Pests & Diseases
Susceptible to common rose pests including aphids, thrips, and spider mites. It is noted for its exceptional resistance to fungal issues such as black spot and powdery mildew.
